is merely an accidental state of this species.—Brit. Evs.: Leight. 
nm. 2. 
This differs from R. scopulorum chiefly in the absence of any chemical 
reaction of the medulla. The thallus is variable in size and in the 
character of the laciniw, and is often roughish with spermogoniiferous 
pustules. The apothecia, except in the occasionally striatulate receptacle 
and the size of the spores, are, as well as the 2 psa similar to 
those of R. scopulorum, though often congested and difform. 
Hab. On rocks and boulders in maritime districts, rarely on hills at a 
distance from the sea.—Dzstr. General and abundant on all the rocky 
coasts of Great Britain, the Channel Islands, and probably also of Ire- 
land.--B. M.: Island of Guernsey. Leigh Tor, Dartmoor, near Ply-

A much dwarfed condition, being only 3 in. to 1 in. in height, with the 
lacinie often black at the apices. The apothecia are small and usually 
numerous. : 
Hab. On dry exposed rocks in maritime tracts — Distr. Local, though 
plentiful where it occurs in the Channel Islands, S. and W. England, and 
in N.E. Scotland ; probably to be detected elsewhere.—B. M. : The Vale, 
Island of Guernsey. Wembury, Devonshire; Fowey and near Penzance,

(1870) p. 159.—Thallus somewhat small, thick, subopaque, tuber- 
culoso-difform, rigid, shortly laciniate; lacinie dilated, sparingly 
divided (medulla K—). Apothecia chiefly terminal.—Cromb. Journ. 
Bot. 1874, p. 147; Leight. Lich. Fl. ed. 3, p. 90. 
Analogous to var. ixcrassata of R. scopulorum, from which it differs in 
the absence of any chemical reaction of the medulla. The thallus is 
sometimes terebrate in old plants. Our British specimens are rarely 
fertile.
